BACKGROUND OF THE INVENTION

This invention relates to a camera having an internal data imprintingdevice. More particularly, the invention involves a camera capable oftaking pictures in both a full size format and a panorama size formatwherein each format has a distinct data size and data position upon afilm.

Embodiments of cameras having data imprinting devices have employedfixed position systems wherein a size of a data image remained constantregardless of a format mode selected. In such systems the light path isfixed, for example, at a lower part of the film with the charactersbeing imprinted in a center of a frame. Since the position of the dataremained constant, data could not be imprinted within a framed area of apanorama size format picture.

Another embodiment of a camera with a data imprinting device, asdisclosed in Japanese Laid-open Patent Publication No. 63-27823, employsan optical system having movable elements. The data imprinting devicedisclosed in this publication comprises a plurality of optical elementscapable of moving to appropriate positions dependent upon a selectedformat. A first optical element is disposed at a first position in orderto produce characters having full size format dimensions. A secondoptical element, preferably with a different enlargement, moves from afirst position to a second position in order to imprint panorama sizeformat data images which are smaller than those of the full size format.Thus, the two optical elements provide appropriate character sizesrespectively. However, movement of the first and second optical elementsnecessitates increased system complexity and is prone to produce blurreddata images due to inaccuracies in the positioning of the opticalelements.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, there is shown a first embodiment of the presentinvention having a camera body 1 with a dark chamber 2 integrally formedtherein. Light, from an object to be photographed (not shown), isfocused by a photographic lens L, through dark chamber 2, onto a surfaceof a film F when a shutter 52 is opened. An aperture 1c, in a backsurface 1b of camera body 1, allows the light to strike a photosensitivesurface of film F. Film F is drawn across aperture 1c into a take-upspool chamber 3A by a take-up spool 11, from a feed spool chamber 3B.The feed spool chamber 3B and take-up spool chamber 3A are bothintegrally formed within camera body 1. A partitioning wall 1a separatestake-up spool chamber 3A from dark chamber 2.

Referring to FIG. 2, aperture 1c is flanked, on upper and lower sides,by inner rails 4a and 4b, respectively. Inner rails 4a and 4b protrudeinto dark chamber 2 from back surface 1b of camera body 1. A pair ofouter rails, 5a and 5b, are disposed outside inner rails, 4a and 4b, andprotrude from back surface 1b further into dark chamber 2 than innerrails 4a and 4b. Outer rails, 5a and 5b, guide film F (not shown) as itis drawn across aperture 1c. A first pressing roller 12 is biased towardtake-up spool 11 by a leaf spring 12a affixed to partitioning wall 1a. Aboss 11a, disposed on take-up spool 11, engages a sprocket perforationin film F (not shown) and winds film F around take-up spool 11 astake-up spool 11 is rotated in a counterclockwise direction.

Referring back to FIG. 1, a back cover 6 encloses a rear of camera body1, and a front cover 7 encloses a front of camera body 1. A pressureplate 8, disposed on an inside surface of back cover 6, biases film Finto contact with inner rails 4a and 4b shown in FIG. 2. A secondpressing roller 13 is biased toward take-up spool 11 by a leaf spring13a affixed to back cover 6. Pressure imposed by first and secondpressing rollers, 12 and 13, upon film F ensures tight winding of film Fon take-up spool 11.

A circle Cmax, shown by a double dash line, indicates the maximumdiameter of film F wound on take-up spool 11. When the diameter of filmF is at or near maximum circle Cmax, roller 12 is urged into a position,shown by a two-dots-dash line into a recess 3a in partitioning wall 1a.Roller 13 is similarly urged outward to a position shown by atwo-dots-dash line.

Referring again to FIG. 2, a data imprinting device includes a pluralityof light emitting elements 21, preferably light emitting diodes (LEDs),disposed in a line on a substrate 22 in a direction perpendicular to thephotosensitive surface of film F. Substrate 22 is mounted on a topsurface 1d of camera body 1 such that emitted light from light emittingelements 21 passes through an aperture 1e in top surface 1d of camerabody 1. A driver circuit (not illustrated), for light emitting elements21, is also disposed on substrate 22.

An optical system including first and second prisms 23 and 29, isdisposed in a substantially triangular space S (indicated in FIG. 1)defined by back surface 1b of camera body 1. The prisms, 23 and 29reflect the emitted light 90 degrees such that reflected light passesthrough apertures 1f and 1g, respectively, thereby imprinting data uponthe photosensitive surface of film F (not shown). A shutter plate 36,having an aperture 36b, is disposed at a rear side of camera body 1. Theshutter plate 36 is shown in a first position, used for a full sizeexposure, wherein aperture 1f is unobstructed, permitting the emittedlight to pass therethrough and expose film F (not shown) while aperture1g is obstructed. Alternatively, shutter plate 36 may be moved upwardinto a second position such that aperture 1f is obstructed and aperture1g is aligned with aperture 36b, permitting the emitted light to passtherethrough and expose film F. The second position allows imprinting offilm F in a panorama size format.

Referring to FIG. 3, a mechanism for the operation of shutter plate 36includes an upper screen framing member 31 attached to shafts 32, 32.Shafts 32, 32, pass rotatably through partitioning walls 1a and 1k, asshown in FIG. 1, allowing upper screen framing member 31 to rotatethrough an angle. A screen frame actuator 33 has a slot engaging a pin31b on an ear portion 31a of upper screen framing member 31. An externalcontrol (not shown) is used to displace screen frame actuator 33 from afull size frame position to a panorama size frame position, shown by adouble dash outline in FIG. 3, thereby rotating upper screen framingmember 31 from a full size frame position, shown by the solid outline,to a panorama size frame position, shown by the double dash outline. Inthe full size frame position, upper screen framing member 31 has acropping portion 31', shown in FIG. 1, which is raised therebypermitting exposure of an upper portion of film F. In the panorama sizeformat position, cropping portion 31' is lowered thereby masking theupper portion of film F.

A lower screen framing member 34 is similarly mounted upon shafts 35,35, which pass rotatably through walls 1a and 1k, as shown in FIG. 1.Lower screen framing member 34 has a geared portion 34c engaged with ageared portion 31c of upper screen framing member 31 such that motion oflower screen framing member 34 mirrors that of upper screen framingmember 31, thereby cropping the lower portion of film F with a croppingportion 34' shown in FIG. 1.

The shutter plate 36 has an ear portion 36c with a slot 36a therein. Aboss 34a, of lower framing member 34, engages slot 36a. Shutter plate 36is slidably mounted such that it is actuated along a vertical axis inaccordance with a position of lower framing member 34. Shutter plate 36is shown in the full size position, covering aperture 1g while aperture1f is uncovered. Alternative methods of implementing a shutter mechanismwould be recognized in view of this disclosure by those skilled in theart. For example, pivoting shutters and rod-type linkages may beemployed. Such methods, while employing alternative actuating systems,remain within the scope and spirit of the present invention.

An optical system comprises an optical system shaft 24 which has anupper taper 24a and a lower taper 24b supporting prisms 23 and 29,respectively. Upper taper 24a is set back further from the surface offilm F than lower taper 24b thereby permitting emitted light from lightemitting elements 21 to reach both lower taper 24b and upper taper 24a.Prisms 23 and 29 both have reflecting surfaces on planes of upper andlower tapers, 24a and 24b, respectively, for reflecting the emittedlight onto the surface of film F. Reflected emitted light of prism 23crosses a path of incident emitted light of prism 29. The crossing oflight paths permits both prisms, 23 and 29, and their respectiveapertures, 1f and 1g, to be in a line in a plane perpendicular to filmF, thus allowing the optical system shaft width to be narrow along anaxis perpendicular to the plane of FIG. 3.

A roller 25 contacts an inner surface of film F and a spring 26, alignedwith roller 25, contacts an outer surface of film F biasing film Fagainst roller 25. Friction between roller 25 and the surface of film Frotates roller 25 in step with the movement of film F. Roller 25 iscoupled to a slit wheel 27 by a shaft 25a. A conventional photointerrupter 28 encircles the edge of slit wheel 27. Photo interrupter 28includes a light source in one of its arms and a photo detector inanother of its arms. Each time a slit in slit wheel 27 passes betweenthe light source and the photo detector, the photo detector produces apulse signal which indicates a length of film F passing roller 25. Itwould be realized by one skilled in the art that alternative means oftracking film advance exist such as magnetic hall effect devices andvariable resistance devices. Use of such devices is within the scope andspirit of the present invention.

The pulse signal from photo interrupter 28 is applied as a feedbacksignal to a controller 40. Controller 40 comprises a CPU, ROM, RAM andperipherals for controlling a motor driver 41 for driving a film advancedrive motor 42. An exposure format detecting switch 43 is controlled bya position of screen frame actuator 33 and signals to controller 40 aselected exposure format. The exposure format detecting switch has abrush 43a, positioned by screen frame actuator 33, which engages astationary portion 43b. Signals produced by controller 40 are applied toLED driver 44. LED driver 44 produces drive signals for the LEDs oflight emitting elements 21. The timing of the drive signals applied tolight emitting elements 21 is controlled according to whether full sizeor panorama size format mode is selected. It is recognized thatembodiments of the present invention may employ other means forimplementing the controller without departing from the scope and spiritof the present invention.

Contact between brush 43a and stationary portion 43b produces anelectrical signal which indicates to controller 40 that the panoramasize format is selected. When the panorama size format is selected,controller 40 actuates LED driver circuit 44 such that positioning andtiming of the imprinting of data produces imprinted data in the panoramaformat. Conversely, when brush 43a and stationary portion 43b are out ofcontact, controller 40 initiates imprinting corresponding to thatrequired in full size mode.

Referring to FIG. 4, a backside view of the camera shows shutter plate36 positioned in the full size format position with aperture 1f open andaperture 1g occluded. Upper and lower screen framing members, 31 and 34,are adjacent to shutter plate 36 and its ear portion 36c. Roller 25 isshown disposed below inner rail 4b and shutter plate 36. Film F, showncut-away to the right, is aligned so as to pass over roller 25 whichsignals to controller 40 the amount of film passing. When the panoramasize format is selected, shutter plate 36 rises upward and aperture 36bis aligned with aperture 1g. Thus, reflected light passing througheither one of aperture 1f and aperture 1g is used to imprint data uponfilm F as it travels. The travel of film F, as sensed by roller 25, isused to coordinate a sequentially implemented longitudinal imprintingpattern upon film F. A vertical imprinting pattern is determined by aselection of LEDs of light emitting elements 21, as depicted in FIG. 3,which are simultaneously illuminated. Alternative embodiments 6f thepresent invention may employ differing light emitting devices or lightcontrolling devices without departing from the scope and spirit of thepresent invention.

Referring to FIG. 5, format layouts are shown with the panorama sizeformat cropping shown in double dash lines superimposed upon the fullsize format cropping. Imprinted data 101 is in a position used in thefull size format and imprinted data 102 is in a position used in thepanorama sized format. The vertical positioning of imprinted data, 101and 102, is determined by the positioning of apertures 1f and 1g,respectively. Imprinted data 102 of the panorama size format isaccordingly located inward from imprinted data 101 of the full sizeformat. A pattern of imprinted data, 101 and 102, as noted above, isproduced by selective sequential illumination of the LEDs of lightemitting elements 21 in coordination with the travel of film F pastapertures 1f and 1g. Imprinted data, 101 and 102, of the figure mayrepresent, for example, the date of the exposure. It is recognized thatvarious other types of information and data may be imprinted upon theexposure. As examples and not limitations, such data may include anf-stop setting, a shutter speed setting, light levels, and photoidentifiers or titles. It is further recognized that embodiments of thepresent invention may include peripherals that interface with the camerato allow data to be entered for imprinting purposes.

Referring to FIG. 6, the optical system and the mechanism for theoperation of the shutter plate 36 is shown in the panorama size formatmode. The incident emitted light of prism 29 crosses the path of thereflected emitted light of prism 23 and is reflected by prism 29 uponthe surface of film F. Aperture 36b, of shutter plate 36, is place inalignment with aperture 1g of the optical system, permitting the emittedlight to strike film F at a lower position than in the full size framingposition, wherein the reflected emitted light passes through aperture1f. Shutter plate 36 covers aperture 1f of the optical system therebydisabling full size format data imprinting.

Referring to FIG. 7, the alignment of shutter plate aperture 36b withthe optical system aperture 1g is shown from the rear side perspective.Cropping portions, 31' and 34', of upper and lower framing members, 31and 34, respectively, are shown in their panorama mode positions, andaperture 1f is covered by shutter plate 36 thus disabling the imprintingof data in the full size format.

Referring to FIGS. 8(a) and 8(b), the optical relationships of prisms 23and 29 are shown wherein a size of the imprinted data is varied from thefull size format to the panorama size format. While prisms 23 and 29 inprior figures have a reflecting surface, biconvex lenses, and aretriangular in shape, prisms 23 and 29 are represented in FIG. 8 assimple biconvex lenses in the interest of simplicity. An arrow Y0 at theleft of FIGS. 8(a) and 8(b) represents an object height of lightemitting elements 21 while arrows, Y1 and Y2, on the right siderepresent image heights of the resultant imprinted data. While objectheight Y0 is constant in both figures 8(a) and 8(b), image height Y1 ofthe full size format imprinted data is larger than image height Y2 ofthe panorama size format imprinted data, shown in FIG. 8(a). The ratioof object and image distances, S₁ to S₁ ', is determined by a positionof prism 23 in optical shaft 24 with respect to light emitting elements21 and the surface of film F. The focal length f of the lens may then beselected to produce a focused image based upon this ratio. Similarly,the ratio of object and image distances, S₂ to S₂ ' is determined. It isrealized that alternative embodiments of the present invention mayemploy other light directing and focusing means, such as mirroredsurfaces and independent lenses, in place of the compound lens-prism ofthe presented embodiment, without departing from the scope and spirit ofthe present invention.

The embodiment of the present invention, as described above, has prism23 in a line with prism 29 in a vertical plane perpendicular to thesurface of film F and set back further from film F than prism 29, asshown in FIG. 6. This arrangement results in image distance S₁ ' beinggreater than image distance S₂ ' and the crossing of paths of thereflected emitted light of prism 23 and the incident emitted light ofprism 29. Furthermore, the selection of the distances S₁, S₂, S₁ ', andS₂ ' permits the use of a single type of prism having the same focallength f for both prisms 23 and 29. Finally, the crossing paths of lightpermits the in-line arrangement thus reducing the width of the spacerequired for the optical system allowing a more compact camera to beproduced.

Referring to FIGS. 9 and 10, a second embodiment of the presentinvention is shown having features similar to those of the firstembodiment, described above, except as note herein. An optical systemshaft 124 has upper and lower tapers, 124a and 124b, upon which aremounted prisms 123 and 129, respectively. Prisms, 124a and 124b, arelocated a substantially equal distance from the surface of film F andare thus in a line with each other in a plane parallel with film F. InFIG. 10, it is clear that prisms, 123 and 129, are offset from eachother. This offset arrangement produces an optical system requiring lessdepth in camera body 1 than the first embodiment of the presentinvention since there is no crossing of light paths.

Referring to FIG. 11, wherein optical path lengths of the secondembodiment of the present invention include image distances S₁₁ ' andS₁₂ ', representing distances from film F to prisms 123 and 129respectively, being substantially equal. Object distances S₁₁ and S₁₂represent distances from light emitting elements 21 to prisms 123 and129 which are represented as simple biconvex lenses for purposes ofsimplicity. Object distance S₁₁ is shorter than object distance S₁₂.Accordingly, image height Y1 produced in the full size format is greaterthan image height Y2 produced in the panorama size format. Focal lengthsf₁ and f₂ of prisms 123 and 129 are either selected independently inorder to focus images Y1 and Y2, or are equal provided that there is asufficient depth of field for images to be adequately focused. It isrecognized by those skilled in the art that various combinations offocal lengths and object and image distances may be chosen based uponrequirements of a system.

Referring to FIGS. 12 through 15, there is shown a third embodiment ofthe present invention which is similar to the first embodiment except asnoted herein. A shading plate 136 is shown in a full size formatposition in FIGS. 12 and 13 wherein an upper portion of shading plate136 covers aperture 1g and ends a distance H from aperture 1f. Shadingplate 136 is in the panorama format position in FIGS. 14 and 15 withaperture 36b aligned with aperture 1g thereby permitting data imprintingin a panorama size format. Aperture 1f remains uncovered thus permittingsimultaneous full size format data to be imprinted, however, the fullsize format data does not affect a photographed image because the fullsize format imprinting is on an area of film F which is masked by uppercropping portion 31' of upper framing member 31.
